Abstract: Upon detecting a lane-change trigger to move an ego vehicle from a current lane to a target lane, a target vehicle is identified in the target lane. Then a set of candidate trajectories is built for the lane-change maneuver by, for each of the target vehicles in the target lane: determining a set of constraints for a lane-change maneuver based on current data collected in the ego vehicle, including speed and distance constraints for the ego vehicle, and adding to the set of candidate trajectories, from a stored set of trajectories, a candidate trajectory for the lane-change maneuver that satisfies the constraints for the lane-change maneuver. Upon determining that the set of candidate trajectories has been built for each of the target vehicles, an optimal trajectory is selected from the set of candidate trajectories. A longitudinal acceleration of the ego vehicle is commanded based on the optimal trajectory.

Abstract: Chemical formulations for chemical products can be represented by digital formulation graphs for use in machine learning models. The digital formulation graphs can be input to graph-based algorithms such as graph neural networks to produce a feature vector, which is a denser description of the chemical product than the digital formulation graph. The feature vector can be input to a supervised machine learning model to predict one or more attribute values of the chemical product that would be produced by the formulation without actually having to go through the production process. The feature vector can be input to an unsupervised machine learning model trained to compare chemical products based on feature vectors of the chemical products. The unsupervised machine learning model can recommend a substitute chemical product based on the comparison.
